Application filed J 11116 16, 1905. Serial No. 265,578-

To all, zohom it may cncern3- s 3- Be it known that I, LEOPOLD BRocKT, a subject of the Emperor of Germany, residing at 80 Matthiasstrasse, Bresla'u, Germany,

have invented. certain new and useful-Improvements in Apparatus for Sorting Articles,

According to Weight; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable 1'0 others skilled in'the' art to which it appertains v to make and use the same. This invention relates to apparatus for sorting articles, such as cardbozrds or the like, according to their weight and comr 5 prises a table acting as a scale and chutes or shelves arranged at-different heights in front of the same, from which the weighed articles can be conveyed rtovarious points. When the/single articles which are to be weighed come successively onto the weighing-table,

thetable sinks to a certain degree, according to the loa so that when the particular article slides 03 the table it comes onto one of the higher or lower situated shelves, accord- 25, ing to its weight. Consequently each shelf always receives pieces of the same weight, so that hereby the different articles are sorted according to weight.

This new devlce is particularly useful in 0 connection with the manufacture of cardboarcl ,-as 'thecardboards made by the same.

machine vary in weight," and the sortin of .the same has had to be eflected hitherto m a tedious manner by weighing each cardboard y hand- In the drawing one form of the invention is shown applied to the sorting of cardboards, Figure 1 bein a longitudinal vertical section,

a is t e fee -.table, coming from the smoothor finishin mechanism. The weighingt a ile is forms by the rollers 11 and 0, over I which the conveying-band d, which runs in the direction of the arrow e, is carried. The

'4' 5 'iiollers'b and c are connected together by the side bars f and are supported by means of the knife-ed 0 bar 9 on the balance-beam h. The balanceeam rests on the knife-edge i, and, together with the wei hingetable, is bal- T e disks m, n, and 0,

' which act as wei hts, are arranged one above the other at s 'ght distances apart in a weight-holder Z, so that when the weight k is moved the differei 5 wei hts o n m are suc- 5 5 sessively raised by he pi lar p, gradually in- "creasing the counterweight ,ofythe balancewould only press against the weight-disk 0 when a cardboard exceeding five, hundred lgiams in weight came onto the weighing-tae. wei hts 0 at m each weigh twenty grams, the tabi remains in its starting position until the weight 0 is overcome, and this occurs when a cardboard weighing more than five hundred and twenty grams comes onto the conveyingband (1. 1f the cardboard weighs more than five hundred and twenty grams, the weightdisk 0 is raised until it strikes against the disk n. table-plate thereby further lowered, however, when a cardboard exceeding .five hundred and forty grams in weight is on the table, and so on. In front of the weighing-table different shelves or chutes g 1" s t are arranged one above another and lead to conveying-bands u 'v w as, which are driven in the direction of the arrows from the shaft of the roller 1) by chain-gear y z 12 or in some other suitable manner. The shaft of the roller 1) has at one end a band; ut any other suitable means may be rovided for im arting motion to said shaft. Ihe-conveyingands u to m are of different lengths, so that the cardboards conveyed thereon are carried to different points. order to facilitate the removal of the cardboards which have been sorted, trolleys 3 4 5, which runon rails 6 7 8, are arranged behind each conveying-band.

The action of the device is-as follows: Each cardboard reachtvs the conveying-band d from the table a of the smoothing mechanism and is pushed thereby in' thedirection of, the arrow e. According. to the weight of the cardboard the weighing-table either remains in its starting position or sinks so that it. comes before the shelf 8 or t,-accordingly as none of the disks 0 1 mm several of them. are raised. by the weight of the cardboard. According to the previously-mentioned example the cardboa'rds we1ghing from five hundred to five hundred and twenty grams reach the shelf 9, those weighing from five The disk n is only raised; and the ulley 10 to receive a driving belt or hundred andtwenty-one to five hundred and forty. grams the shelf 1", those weighing boards coming from the shelf 1 onto the conveying-band a", reach the trolley 3'. The convey'ing-band w takes the cardboards ironsv the shelf s and conveys them to the trolley 4;

The oardboards from the shelf 1' are conveyed yee edjustedl orother weighf fl this can be easily done by shifting the Weight is and.

shelv rran es a ntall mounted,

by the conveying-band v to the trolley 5,

while the conveying-band it conveys the cardboards from the shelf g.

The; Weighing device acting in stages may of course be replaced by one acting continuously, and this is advisable when more exact Weighing is required. The shelves g rs tare in such case not fixed, as in the example given, butare better arranged adjustably, so

that the weighed object can be removed from the table whatever may be the extent to whichthe table is lowered.

Ifjwith the form ilhlstrated the device is to changing the disks on, and m. o What I claim, and desire to secure by Let ters Patent, is-- ing to-weig t, comprising a scalebeam, a piy- I v Yertieallyswingin fee-d table having its free end supported; y said acal'e l ea n, and a 'lnraiity of snperposed jacent to "tlie.free or The card-- aratus for sorting articles accordswinging end of said table to receive articles therefrom. i p
